Whether you’ve just built or bought a brand-new PC, or if you’ve gained an enlarge computer, you need to stress test your CPU regularly. Stress experimentation ensures maximum stability and helps you find out your pc limits. Certain your stress and anxiety test goes as smoothly as feasible by detecting and also hibernating all background applications with bsci-ch.org TuneUp.

What is a CPU tension test?

Stress-testing a CPU way running it at maximum capacity for a sustained duration of time to advice its stability. Stress trial and error software supplies a variety of approaches to press your CPU to 100% volume for one hour or more, climate analyzes that is performance. CPU stress tests are likewise known together CPU pack tests.

We’ll present you how to use the most famous PC stress testing tools, then define how stress experimentation helps preserve your computer’s health.

How carry out I stress and anxiety test mine PC?

Follow this procedure to anxiety test her PC:

Choose and download a stress testing tool.

Run the stress and anxiety test while security your CPU temps.

The outcomes of your computer system stress check will give you one idea of her PC’s in its entirety health and stability. It’s crucial to execute a CPU stress test before overclocking your CPU — otherwise, you might push points too far.

How to prepare because that a computer stress test?

To make certain your CPU anxiety test operation properly, prepare your computer by shutting down any kind of programs that won’t it is in used during the test. Then, monitor her CPU temperatures. This is how:

Open bsci-ch.org TuneUp, walk to Speed Up, and also click Background & startup programs. Sleep setting will finding unnecessary programs and temporarily deactivate them to ensure your test delivers the most accurate results possible.


Monitor her CPU temperatures: don’t let her CPU temperature exceed 90°C for an extensive periods.

What space the finest tools for a CPU fill test?

Our recommended CPU stress experimentation tools space Prime95, AIDA64, HeavyLoad, and Intel BurnTest. These every work similarly to one another, through minor differences. Here, we’ll display you just how to use several of the ideal tools to stress test her PC.


Prime95 is among the most renowned CPU stress experimentation tools the end there. It uses the Mersenne prime technique, which provides nonstop use of her processor’s FPU (floating point unit) and also integer ability while likewise testing its assorted caches (L1, L2, L3).

Here’s how to usage Prime95 to do a computer stress test:

Launch the tool and select Just stress and anxiety testing. Choose the mix option, which anxiety tests every cores and also caches. Climate click OK.


At this point, the test will begin. Your processor and also all its cores will instantly reach 100% capacity, and your computer’s fans will kick into action.


As with various other stress trial and error tools, you should let this one run for about an hour (or if girlfriend really desire to understand the best limits: a day).


With 25 year in the industry, AIDA is a substantial suite of tools to display and also diagnose your whole machine. It’s available as a premium product, however you can additionally download a totally free trial for a quick PC stress and anxiety test.

AIDA64’s system stability check simulates a reality workload for her computer. Here’s just how to launch it and also perform a CPU fill test:

In the Benchmark category, you have the right to test her system and also compare it to various other PCs.

To start the computer system stress test, click on Tools and select System stability Test. As soon as you’re ready, click Start.

During this test, you can conveniently switch earlier to the key AIDA64 home window and go to Computer and also Sensor. Here, you deserve to watch end the CPU temperature and also see how fast your fans room rotating.

As lengthy as the temperature stays listed below 90°C, you should be fine. Let it operation for a couple of hours and see if your pc remains stable.


Another great stress trial and error tool is HeavyLoad. It doesn’t simply stress check the CPU, however it likewise lets you monitor your GPU temp together your computer is placed through that paces.


Just launch the app, choose CPU Usage, and also hit the Play button at the optimal to start the computer stress test.

Intel BurnTest

Intel Burn test isn’t an official Intel tool, but it’s one of the easiest computer stress tests the end there to use.


Open the app, click on anxiety Level, and also select Maximum. Hit the Start button to begin the CPU fill test. Let it run for a while and also see if her PC have the right to handle the stress.

Why need to I stress test a CPU?

You must stress test her CPU to advice the security of its performance — a pc stress check runs her CPU at complete speed and also subjects it to high temperatures. Constantly stress test her CPU before overclocking the — if her CPU stops working the stress and anxiety test, that won’t take care of an overclock.

Don’t shot this at home. There are better (and safer) ways to stress test your CPU 보다 by placing it in a frying pan.

Common reasons to stress test her CPU

The ideal reasons to perform a computer system stress check are:

You bought a new PC or laptop. Just gained a brand-new machine? operation it with some stress and anxiety testing and see how it performs. This is vital if you have a super-slim laptop with tiny to no cooling.
